Fi??

Recommended Posts

Kawasaki came out with the new fuel injected KX450F. How much of a difference does FI make? not having to worry about the choke and jetting must be great

Take a look at the 08 Suzuki and read reports from the field. There has now been nearly a full season on the system. EFI ion dirtbikes is still more or less in its' infancy. But it is getting there.

ran into a guy on one of the new FI huskys a week or two ago. he was kind enough to let me spin it around for a minute or two. from the short ride i had on it all was perfect.

The "no jetting" can only work if you have the sensors neccessary to adjust the FI using the current environmental conditions, throttle position, engine temp, RPM and what is going out the exhaust. Any mods to the bike that adjust the intake or exhaust flow usually take some mapping changes if they move parameters close to the edge or outside the stock fuel map.

Look for the rise of an entire industry of add on devices to change the mapping - just like what happened for autos and street bikes.
